Fundamentally Harmonious Over the next few months, we will get a little more serious about the science behind Hi-Res audio. Do not panic, ley-folk, as we will be putting in the hard work and attempting to report our findings in an easily digestible form. We need to begin at the beginning. Sound is a complex […]
